Serial No. 586,426.

To cZZ 107mm t may concern 'le :it known that ll, HUGH l?. Meh/lineari, a citizen ol the United States, residing at Baltimore, in the State of lvlaryland, have invented cer'ain new and useful. Improve inents in Brushes, of which the following is a speeication.

rlhis invention relates to improvements in brushes and has particular reference to a brush for use in painting and decorating.

The object of the invention is to provide an improved construction of brush whereby to securely hold the bristles about and to the handle, and to protect the lower end of the wood handle from the fiction ot liquids that causes the wood to swell and break the ceinent or rubber binder.

The invention :is illustrated in the accompanying drawing wherein,--

Figure l is a side elevation oit' a complete brush. Fig. 2, an enlarged vertical longitudinal section through the lower portion of the handle and the devices securing the saine to the buttends oit the bristles. Fig. 3 is a vertical cross-sectional view ot the saine, and Fig. 4t, a. perspective detail ol the `flanged central wedge.

In the drawing, l, designates a wooden block having an upwardly-projecting handle, 2, and a depending central plug or rib, 3. This plug or rib is long and narrow in a transverse direction and projects centrally from the bottoin side ot' the block leaving an over-hanging shoulder, ll. on the wooden block along the opposite sides and around the ends of the plug.

The bristles, 5, have their butt ends, G, bound together by a suitable cement or vulcanized rubber and said butt-cnds are encircled by a suitable band, 7 to retain them. A metal. shell, 8, is provided at the center oit the butt-ends of the bristles and has long sido walls, 9, and narrow end walls, 10, both ot which incline at their lower portion, 11, and nierge. A horizontal flange, 12, is provided at the upper open end oit' the shell which projects outwardly over the butt ends et the bristles and toward the encircling band, 7. rlhis flange, 1Q, 4is ljnovidcd in the present instance with a plurality of perforations, 13, which are disposed over the inner ends ot the bristles so that the cement or rubber when in a plastic condition can squeeze into said l ertorations and 'torni a key to secure the shell-Harige and ln'istlc-ends together.

'.lhe plug or rib, 3, has its lowerI side and end portions inclined to correspond to the lower inclination ot' the side and end walls oil? the shell so it inay snugly tit down therein and perinit the overhanging shoulder, 1l, on the block to scat close on the horizontal flange, 12, olf the metal shell. A suitable tas toning such as a drive screw, llt, extends up through the closed inclined lower portion ot' the shell through the central plug, 3, and into the block, il., and tastenings, l5, extend horizontally from the band, 7, through the cemented ends ot the bristles and also through the inetal shell and central plug, which fastenings, together with the drive screw, lll., securely hold the bristles and shell to the central plug. An outer itcrrule, 16, encircles the block, l, and also the band, 7, and is held to the block by nieans ot' nails, 17.

By nieans oit this construction it will, be seen that the lower end of the block, l, and plug, 3, which is At'orlned ol wood is covered with metal and is thereby protected from the action oi liquids that often causes the wood to` swell and consequently break or crack the cement or hard rubber and the band that binds the ends o't the bristles togcthcr.

Having thus described iny invention what l claiin and desire to secure by Letters Patent is,--

A llat brush having a handle with a brush block at the inner end ot the handle which block has a erosswiseextending narrow plug projecting downnun'iflly troni the center oit its under side which plug is of less width and thickness than the width and thickness ol the brush block whereby to leave an ii'itegral ovm-hanging Ishoulder on the block all the way around the narrow plug; a nietal shell having a long and narrow socket to receive the plug on the block and also having an integral Voutwardly-exteinling flange around its upper edge which (lange is of less width than the over-hanging shoulder on the block; ineans extending into the plug :trom the under side ot the shell socket to secure the shell to the block; bristles having their butt ends tending both belowT and above the flange on around the sides and ends of the shellk and the shell. lo beneath.theintegral"ontwardflnge :ofthe In testimony whereof I'ax mysgnature latter; a' band havngan edge againstthe' in presence oftwo Witnesses.
